To all who-m t may concern:

Be it known that I, JOHN lvlarznnnn, `a citizen ofthe United States, andresident of Cleveland, in the county of Cuyahogaand' 5 State of Ghio,have invented' certain new and useful Improvements in Revolving `WindowSashes, of which I hereby declare the following to be a full` clear, andexact description, such as will enable others skilled in the art towhich it appertains to make and use the saine.

The objects of the invention are to provide a simple and efficientpivotal support for a swinging window sash, especially for a swing 'sashmounted betweenl casing strips. Y

The pivotal support is also designed to provide means for preventing thepassage of light and moisture between the sash and the casing strip whenthe sash is closed,

without interfering in any way with the' movements of the sash eitherwhen swung upon its pivots or when raised and lowered in its frame. v

The invention comprises, a pivotal support'formed in two portions, oneportion being provided with a. longitudinal V shaped ridge, and thelother portion provided with a n. corresponding V shaped groove, theaforesaid ridge and. groove registering with4 and being continuations ofasimilar ridge and groove in the meeting edges of the sash and thecasing strip.

The portions include a metal plate mounted upon the sash and providedwith an opening at the bottom of said Vshaped groove, and with a numberofy shallow recesses spaced apart in a circle about the central opening,and an opposed plate mount-ed 40 in the casing strip, and provided witha central projection adapted to pivot in said opening in the otherplate, and also provided with spaced projections orilugsprojecting fromthe summit of said'Vshaped ridge, and' adapted to engage in turn withsaid recesses.

It..includes means for securing the said plates and casing stripresiliently together, and for securing the plate for said sash to saidsash. l r .n

It includes fastening devices for said sash for preventing outsidersfrom revolving the sash and also adapted to draw the. sash and easingstrip tightly together.

" yThe pivotal parts are The invention i is hereinafter described, shownin the accompanying drawings andA specifically pointedoutin"the'claiins'.y

In the accompanying drawings, Figiv 1, is a front elevation of a windowsash, a! por` tion being broken away to show thedevice; Fig.' 2Q, is avertical section showing the two plates; and resilient attaching meansthere for; Fig. 3, isa perspective of the plate at.- tached tothe sash;Fig. l, is afperspective of the plate attached to vthe easing/strip',Fig; 5, is a view of the back ofthe plate.' attached to the sash Fig. 6,is a perspective so i of the fastening means'` employed,which i servesalso to draw thesasyli and casing In these'views A, 'representsthe'sash, and.

The Opposed edges of the sash and casing" strips are provided withweather excluding means comprising, the longitudinal central V. shapedridge C,.upon each casing strip, s.

` andthe central V shaped groove D, iny the engaging edge of thesash.Thispconstruc-ftion'permits the sash to revolve easily in` ythe saidstrips, but makes' a weatherftight joint therewith.

A'iplate' E,.i`s attached by meansof F, F, to Yeach side of the sashvand'this plate' is providedwith a V shaped longitudinalfV groove Gr.` vf AInthe center of thisgroove is shown' anv opening 'I-I, and about `theopening are cir!r cularly spaced a number of recesses I, I, I, which arepositioned, t-woin the bottom off the groove, and the 'othersr uponvth'esloping sides and face of theplate. l

The opposed plate J, .is set in a recessin the edge of the 'casing stripand is provided with a V shaped longitudinal ridge K, uponv the .apex ofwhich' is'. positioned' thel pivoty wristl L, which is inserted in ftheopening I-I, in the other` plate,and upon the ape-X` of` 'the ridge. areApositioned the projecting spaced lugs or bossesv M, M, ,which areadapted toV enter the recesses I, I,I, in the `other plate in turn asthev sashI revolves upon the casing. 1

A bolt "or rivet `O., passes lthrough v:bothV .constructed as fli R, ofthe rivet, and holds the parts together.

The bolts or rivets O are extended and project longitudinally at Bbeyondthe casing strips and are inserted in openings O in the windowcasing. Upon these'eXt-ensions of the rivets the sash strips aresupported, in such a manner that they will yield when the sash isrevolved and will be returned by means of the springs P, P. Collars, O2on these pins force back the casing strips when the window sashes arerevolved.

ln Fig. 6, .the fastening devices for'the sash are shownl which. producetight jointsy between the sash and strips and prevent the` sash frombeing turned .outwardly at the bottom.

Here S,`is an eye normally secured to the casing strip and I, is, ahorizontal spring plate for-projecting tongue secured to the sash, whichengages the eye when the sash is. closed. VIt is understoodthatthe lowerrail of the lower sash swings outwardly away from the operator when thesash is ope-ned and towards the operator when the sash is closed.v V, isa latch pivoted upon the casing which can be engaged with the openinglV, in the projection T, when the sash is closed and prevent the Sashfrom being revolved.

Having described the invention what I claim as new and desirel to secureby Letters Patent is:

l. lIn a window structure comprising a casing and a sash therein, thelcombination with a stile member 4of said sash, .of a strip memberinter-posed forlateral movement be tween said stile and said casing,means for Y pivotally connecting said 'members and means preventing saidstrip from turning with said sash, said members having respectively aninter-engageable ridge and groove, and, the first mentonedmeanscomprising a pairv of plates, one. having av ridge and the other agroove respectively alined with the first mentioned ridge and groove,and one plate having a tubular boss and oppositely d sposed projectionsspaced therefrom and the other a central boss receiving opening andspaced depression disposed therearound to releasably receive saidprojections, a pin passing through said boss, said Central open7 ing andsaid strip, and provided with a head, and a collar disposed at. oppositesides of said strip, and a flat springinterposed between said head andthe adjacent plate.

2. In a device for the purpose described, in combination, va casing, asash therein, oppositely disposed, non-rotatable laterally movable sidestrips in which said sash is pivoted for swinging movement, the verticalmeeting edges of said sash and strip members being provided withinter-engaging longitudinal ridges and grooves, opposed plates upon theadjacent edges of said niembers, said plates being provided respectivelywith corresponding grooves and ridges, the plates having ridges beingalso provided with central tubular bosses, and with opposite spacedprojections spaced 'therefrom and the vplates 'having grooves havingalso central openings to receive said bosses and spaced circularlyarranged depressions adapted to receive said spaced projections, pivotpins passing through said central openings Y and bosses in said platesand through said strips, each of said pins having a head at one end anda collar engaging the adjacent stripsy at the other end, and a flatspring engaging said head to resiliently hold said plates together, eachpin having a longitudinal extensfon at one end adapted to enter thecasing to prevent raising said sash. i
